No Drawing.

To all whom it may concern Be it known that we, HENRY A. Heel-ins and Harri-1r A. l-luoirns, Jr, citizens of the United States, residing in Vineland, Cumberland. County, and Haddon Heights, Camden County, New Jersey, respectively, have invented a Process for Y reparing an Improved Sugar Product, of which the following is a specification.

Uur invention relates to composition of matter of a chemical or edible nature and the preparation thereof, and it comprises an improved saccharine body having the prop city of keeping various substances with which it may be employed soft and pliant; being particularly available for use as a substitute for glycerin in the arts. Our invention further includes the process of making this improved product.

Our improved product may be used generally a substitute for glycerin, with the or ception that it probably posseses no medicinal values, and additionally, it may be our ployed as a softener and sweetener for food products.

Our invention comprises an improved treatment of ordinary reiinec cane sugar to effect inversion; then arresting such inversion at the critical point in a special manner, and then, if necessary, neutralising any acid that may be present in the finished product. This treatment may involve the addition of water and a suitable acid, preferably phosphoric acid, to the sugar and the heating of the solution to invert said sugar, or we may employ electrolysis to effect inversion. After inversion has proceeded to the desired and predetermined point, We add a quantity of a sugar solution of a lower temperature to lower the temperature of the inverting solution in order to produce a syrup that is at once proof against spoiling (fermenting), and is non-crystallirable; such product remaining clear and keeping indefinitely under usual conditions. Inversion having continued until the polariscope rezu'ling of the solution equals 0; the amount of cool sugar solution added should contain suflicient sugar (sucrose) to raise the polariscope reading of the combined mass to some suitable point between plus fifteen degrees (+15") and plus twenty-seven degrees (+27 the preferred and ideal reading being approximately plus twenty-tvvo and one-half degrees 01-22%).

Our improved product is a thick, odorless body, very pale yellow in color, having the pure sweet taste of cane sugar, and being miscible with water in. all proportions. hemical analysis of the product at a dens ity of about 42 l d-6., and a temperature of F, should show substantially the following:

Invert sugar this iSucrose 29.35% Ash H 0,05% Water by diiierenc 23. 8

@ur improved product is esentially a mix ture of invert sugar and sucrose, inaintaineiil in a liquid state by water; tree from heavy metals, arsenic, glycerin, chlorides and sulfates.

Our improved product ma, be distinguished from other products by the follow-- ing characteristics. it has a much higher density than that of ordinary cane sugar solutions at the crystalliaing pfllnl) but will remain indefinitely clear, practically color less, neutral, pure syrup of cane sugar. It will. not precipitate crystals of cane sugar; invert sugar, or cane sugar dextrose. the above characteristics and others possessed by our improved product are obtained by controlling the process of inversion of cane sugar so that it shall be stopped and maintained indefinitely at a predetermined point which may be indicated by the usual instruments and methods common in the menu facture of sugar, in order that the relative purities of the invert sugar content of the cane sugar: i. e., dextrose and levulose, produced by the act of inverting the original cane sugar, are in no case high enough to allow crystallization or precipitation of any or all of them; thus maintaining a clear, pure, sweet syrup under the usual climatic changes of heat and cold.

lln preparing our improved product, we may proceed as follows:

To approximately eight barrels of commercial granulated cane sugar (about twenty-eight hundred (2800) lbs.,) we add about fifty (50) gallons of water (416.5 lbs.) and about fourteen (14:) or. of (I. l phosphoric acid; such mixture being then heated at a temperature of about 190 l for a period of approximately one-half (-3) hour. The result of this treatment, if the time and temperature factors are in substaip tial accordance, will to to invert the sugar content of the solution to a polariscope reading of approximately ZQl'O (0), at which point the desired inversion for our purpose is substantially complete. Unless the heating be arrested this point, however, furtier inversion will eccur,'and in order to stop further inversion and at the same time complete the preparation of our improved product we add to the hot mass of inverting sugar syrupabout twenty-two hundred and forty (2240) lbs. of a 70% sugar solution in a relatively cold state (about 60 F.) the result of which addition is to lower the temperature of the inverting mass at once; thereby stopping inversion, and raising the polariscope reading of the combined product or mixture to some point between plus [itteen degrees (+15 and plus twenty-seven degrees (+27 the ideal condition giving a polu-riscope reading of about plus twentytwo degrees (+22) or plus twenty-two and one-half degrees (+22-1-), when the product is ready :tor use. Should tests of the iniished product show an acid reaction, a suitable alkali is added to insure neutrality.

Our improved product, prepared in accordance with the process described, is a pure, neutral, non-crystallizable syrup, nearly water White. It does not precipitate crystals or clouds or cane sugar, invert s u gar, or cane sugar dextrose; contains no free acid, nor any higher percentage of salts than ordinarily found in commercially pure cane sugar.

replace glyerin. is a food product, it may be employed as a syrup, or us a sugar substitute.

in our improved process, inversion of the sugar solution whereby invert sugar is pro duced may be effected by electrolysis, in lieu of the heat and acid treatment. In either instance, the result of inversion is the separation of the pure sugar syrup into the three sugarslevulose, dextrose and sucrose; the quantities of levulosc and dextrose being substantially equal, and the total quantity oi the three sugars equaling about 75 per cent of the total content of the original sugur solution at a density oi? about +12 Bunnie; the l'QlilzillllIlg portion of the solution being water and traces of ash.

We claim:

1. The process which consists in odding water and an acid to granulated cuuo sugar; heating the mixture to about 1530 for approximately one-half hour to invert the sugar content of the solution to u. pola-riscope reading of upproxiniutely Zero degrees; and stopping the inversion. at such reading by adding it seventy per cent (11110 sugar solution at a temperature of 60 ll, thereby producing a mixture having a polariscopc reading between +18 and +522 The processwhichconsistsinpriulucing the inversion of granulated cane sugar syrup and arresting such inversion zit approximutely zero degrees poluriscope rezuling by he addition of a relatively cold seventy per cent cane sugar solution to produce a mixture having a polariscope reading between +18 and +22".
